Abstract:

This paper is a speeding enterprise design of general purpose mechanical strength testing machine. The flexible shaft speeds up under the high speed ，deformation is too large and affect the test questions. Using the Lagrange equations, and establishing the whole equation, then using the Matlab programming to solve the corresponding mass matrix, stiffness matrix, and the matrix of different units set. Using the method of center difference method newmark-beta final Lagrange equation for the numerical solution. Then using the Adams to flexible-body dynamics analysis, it is concluded that the running situation of each part of the flexible shaft system correct.
